The 29-year-old Seahawks safety gave his team a clear ultimatum Monday in an Instagram post of him lifting weights. Thomas wrote in the caption: “Always been the underdog ain’t nothing new. Extend .....if you don’t want me let’s make a trade happen I understand it’s a bizz.”

Thomas is entering the final year of a four-year, $40 million extension he signed in April 2014 that went into effect for the 2015 season. He’ll have a cap hit of $10.4 million this season. The Seahawks could save $8.5 million in cap space by trading or cutting Thomas, who skipped voluntary OTAs and mandatory minicamp in May and June as part of this contract standoff.

“I will not be attending the upcoming mini camp or any team activities until my contract situation is resolved,” Thomas wrote in a statement on Twitter June 10. “I want everyone especially the 12s to know that I want to remain a Seahawk for the rest of my career but I also believe that based on my production over the last 8 years that I’ve earned the right to have this taken care of as soon as possible. I want to have certainty in regards to the upcoming years of my career. I’m going to continue to work my craft and put in work so that I can add to the team and give us the best chance to win. I hope my teammates understand where I’m coming from I believe this is the right thing to do.”

This is just the latest development in a tumultuous offseason for the Seahawks, who have watched their once-vaunted defense dissipate through various means of attrition. In March, they traded defensive lineman Michael Bennett to the Eagles and cut Richard Sherman, who later signed with the 49ers. Then Thomas’ safety partner Kam Chancellor announced his retirement early this month because of a neck injury.

Thomas, who tweeted about retirement after breaking his leg in December 2016 before returning for the 2017 season, stirred the pot back in December, when he ran down Cowboys coach Jason Garrett in the tunnel after Seattle beat Dallas in Week 16 and told him, “If you have a chance to get me, come get me.”

On Monday, deGrom’s agent gave a similar ultimatum to the Mets. "If the Mets don't share [the] same interest, we believe their best course of action is to seriously consider trade opportunities now," he wrote in the statement. "The inertia of [the] current situation could complicate Jacob's relationship with the club and creates an atmosphere of indecision.”
